I've attached a picture of the problem. The problem asks from f'(0) of the function: f(x)=e^(2x)*g(x) g(0)=-5 and g'(0)=3 are given. So the answer I came to was: f'(x)=2e^(2x)*g'(x) However, when I work out the numbers I get: f'(0)=6 This is not right. So I figured I made a mistake a mistake when taking the derivative of f(x). Now I'm stuck because I'm not sure how to derive the function when g(x) isn't explicitly given.
